APPENDIX. 



It was after I had finished this treatise that Mohnike's 

 Blicke auf das Pflanzen-und Thierlehen in den indiscJien 

 Malaienldndern (Miinster, 1883) came into my hands. 

 The author, who was for several years physician 

 and medical superintendent in the Dutch Indies, has 

 given an interesting account of the orang-utan. It 

 appears that this animal is only found in the northern 

 part of Sumati'a, and is more common on the western 

 than on the eastern coast. Even there the orang is 

 only occasionally captured. The Dyaks of Borneo are 

 fond of the flesh of this ape, which they shoot, especially 

 in the interior Of the island, with poisoned darts, 

 projected from a blow-pipe. The wounded part is 

 then carefully cut out. 



Mohnike states that in Borneo Hylohates concolor is 

 called Ouo-ouo by the Malays, and Kalawet by the 

 Dyaks. Dark specimens of Hylohates variegatus are in 

 the Malay dialect called itam, or black Unko, and light 

 specimens are called 2?«<^ or white Unko, A good illus- 

 tration of Hylohates leucogenys is given in the Proceedings 

 of the Zoological Society, p. 680, Plate 42 : London, 1877. 



It should be added to what I have said in the text,
